I have to make a Trebuchet for a large medieval project, a large trebuchet actually, like this one:

I want to make my own, but I have no idea on how to setup the rigid bodies for this particular thing. I googled all day but I can't find any tutorial about it. Only generally speaking tutorials about rigid bodies, but I want something specifically for a trebuchet, and I am searching for a tutorial from modelling process to rigid body physics on how to make a trebuchet and rig/animate it properly.

- but when I try it myself, the stuff falls apart. I followed the tutorial, I did everything right, but it simply won't work for me. The rigid bodies fall apart. They don't work as the tutorial tells me.

I want some more information on how to setup rigid bodies for trebuchets.

Any ideas?

Alternatively, I would be glad if someone would make the rigid body/rigging part for me, then I can make the frameworks/wood beams that are stationary/non-animated parts myself.

Tue, 12 Dec 2017 10:02:26 GMTHello, I'm in need of some serious help.

I'm creating a friend's character and am seriously having some trouble with the feathers.

Currently the furthest progress I've made is creating a hair particle system emitting from a vertex group. I have since converted the strands into the objects (feather textured polygons). However, I have no clue what-so-ever how to style each of them individually with the combing tool.

I've been searching all over the internet for an answer to this but have had no success.

PLEASE someone help me.

Mon, 11 Dec 2017 03:25:59 GMTHello, I'm new to blender. I'm struggling like crazy, my cloth is acting like the stretchiest fabric in the world, and is having issues rendering that it wasn't a few minutes ago. Any ideas as to why??? Thanks in advance for the help, I feel so lost. I also have no clue how to upload the file, I'm just a mess. It's rendering crazy, it's all spiky, and it wasn't before and nothing changed.

Sorry if my question is dumb, I am kind of new to hair editing.

So I decided to try and model an animal during my spare time, but a part of the fur is just.... messed up?

Some hairs are always clipping through a certain portion of the mesh, right on the chin of the model, and end up in its mouth.

I tried using particle editing to pull those hairs off, however they seem to be blocked by the surface of the mesh.
I also tried to switch normals, recalculating inside/outside, but none of these methods were effective.

Is this a comment problem or would it require further informations to solve it?

Hairs going inside the mesh :

And the chin, without any visible hairs when rendered :

Fri, 08 Dec 2017 15:53:26 GMTHi,
As the title says,
I have tried all night and read countless messages and cannot find the answer.
I came close with a youtube video...Hi,

that guy uses IPO curve editor to accomplish this, the IPO curve editor is now called the Graph Editor, and nothing looks the same with the buttons he used.

I need to solve this due to the massive delays inbetween manually aligning the fluid domain to fit my animation.
I need to start baking at near the end of my animation, it takes a while to bake and every time I want to alter and adjust positioning i must rebake..

I have tried right clicking the EYE and CAMERA of the objects in the domain and tried turning off enabled for the water output...
It simply stops and starts the flow of water

cheers

As I have been working on some Xgen and Yeti previously,
I would like to know if it is possible to have a primary clumps, and then a secondary clumps within the bigger clumps??
I know there is no straight forward way to do it in blender, just wanted to know if there is any hack for it??

The...Not sure what the problem is here. I had my fur just as I wanted it and then applied a rigify armature only to find that my fur thinned out. The rigify armature works perfectly and I did not make any chnages to the particle settings. But for some reason when I chose to render the fur after installing the rigify armature, the fur appears thinned out. Here is a sample of the fur before rigify and after on a tail. I would really like to find this myself. Does anyone have any ideas on what may be causing the problem? I know applying an armature, either custom or rigify, should not affect the particle system especially in rest mode.

I checked all particle settings before and after installing the armature and they are the same, I also experimented with the modifier order with no results except a slight change when I moved the particle modifier between the sub surf and the armature modifier. By the way my armature is above my subsurf in the modifier stack. Anyone have any ideas?

Thu, 07 Dec 2017 15:06:22 GMTI've banged my head enough on this. :spin:
And decided to ask for help :)
I am using a plane with some texture on it as the object for my Particle system.
When the particle planes are emitted I would want them to rotate "2 dimensionally"
That means, that I want the planes to be visible wholly, without a 3D rotation (attaching images)
Tried choosing different axes, but each axis, including global Z, makes the planes rotate 3 dimensionally.

Want:

Is there a setting I am missing here?

Tue, 05 Dec 2017 18:02:06 GMTI'm filling a glass container with ornaments. I have an emitter with a particle system, and the balls fall OK and don't pass through the container. But the balls all land at the bottom, and go through each other, so they don't "stack up" and fill the container. So, in short, they don't pass through the container, but they DO pass through each other.

my Grass particle system is hanging half way through landscape system. I suspect it has to do with the locatioon of the lanscape system but cant work it out. Ive rotated the grasses and changed there position but nothing happens. Here is the blend file.

Thu, 30 Nov 2017 00:39:27 GMTLike seriously, I've been using blender for some years and I've never been able to have anything good out of hair particles on animals or creatures. I mean, sure, making hair on a human character, it does the job just fine. But what about filling a whole body of fur from top to bottom in it, taking to account, eyes, mouth, nose, etc?

Has anyone ever managed to do it? I'm starting to think it can't do it at all. And the few examples I've seen are very very few and when I try contacting the person who did it to share how they've done it, I get no response.

Considering that almost no one uses Hair particles for fur, mostly just for hair or grass makes me wonder if it can't at all do it, and the few Blender magicians that do it, keep their secret under lock and key...

There are zero tutorials on this except videos that demonstrate the sliders by making a fur ball which teaches you nothing because I could've just started moving the sliders by myself in Blender and would've gotten the samething, or extremely outdated videos that don't have good results to begin with.

Why is it, that to my knowledge there are no videos, tutorials or paid courses about this? Is blender really incapable of doing that sort of task?

I mean, if it is, please prove me wrong and show me the way because after all of these years in Blender, I have not once had a good result no matter how many times I do it or how hard I try.

Sometimes when i switch to a different baked one, the cache suddenly says "cache out of date". While i didnt change anything or moved anything.

What is the correct workflow of switching between different baked settings and KEEPING them?

I have two emitters and one plane surface. This surface shall reflect (collide) emitter beam 1 but transmit emitter beam 2. Basically a kind of Dichroic mirror where the emitter beam is a laser ray.

Is this possible in blender?
